SECONDARY BATTERY.

Application led October 2, 1920. Serial No. 414,219.

T all whom t may concern: escape of the electrolyte or its passage fromBe it known that I, STEPHEN JENCICK, a cell to cell and also serves as asupport for subject of the Government of Austria, rethe battery plates,as will appear. Above siding at Cleveland, in the county of Cuyathe wallis located an inverted shallow 5 hoga and State of Ohio, have inventedcerdish-like cap or cover 7 also of insulating 55 tain new and usefulImprovements in Secmaterial, its cavity 8 serving to enclose the ondaryBatteries, of which the following is cell connections. The three members1, 5

The batterymay include any suitable 60 The object of the invention is to providenumber of cells and the drawings show a an improved battery of simpleconstruction multiple cell arrangement. For this purso arranged as toenable both the positive pose the insulating casing 1 is provided andnegative plates to be readily withdrawn with two upwardly extendingcross walls either for the purpose of replacement or for integraltherewith, forming three cell cham- 65 inspection and repair, and alsoto simplify bers 11. These cell chambers, best shown the method ofassembling the various parts in plan view in Fig. 4, are approximatelyof the battery in its initial construction. of 8-shape in plan view, orin other words, Further objects of the invention are in the shape of twocircles joined by a con` part obvious and in part will appear morenecting neck, so that the electrolyte flows 70 in detail hereinafter.freely back and forth in each cell between In the drawings, Fig. 1represents a side the two substantially cylindrical portions elevationpartly broken away and in secthereof.

Thespaces are filled by such as rubber, porcelain, a composition or placingthe plates upon a suitable support the like, but may be made of glass ifdeand applying the material thereto in a plassired. This jar may be castwith cavities 2 tic state; after which the surplus material 90distributed upon its sides and bottom to reis removed in any convenientmanner. The

ceive cushioning rubber plugs 3, 4, as shown, apertures 38 may beprovided in any suitable to absorb shocks which might be receivedmanner. These wheel-like members are from surrounding objects such asthe box piled upon each other upon the central sup- 4 5 containing thebattery. The top of the casporting post 14, as shown in Fig. 1. Above 95ing is open and is provided with a flat the upper one of said members ina head 19 peripherally extending surface upon which lying just beneaththe wall 5 and serving rests a fiat horizontal wall 5, formed of as anabutment to secure the shaft and insulating material, the joint beingsealed positive plates to said wall by the nut 20 by a gasket 6. Thiswall prevents the threaded upon the shaft. The upper end 100 of theshaft extends through a bushing 21 to the outside of the cover 7 whereit is provided with nuts 22 for clamping the lead Wire 23.

The negative plates, one of which is shown in Figs. 6 and 7, are in planview of the form of ttWo semiacircles connected by a nee'k '24. 'Theyinc`lude a lead or suitable metal frame consisting of a hub 25, rim 26and ribs 27, all of which are :undercut tas at 28 to support and holdthe negative plastic material 29, as for instance litharge. The plasticmaterial is applied by placing the frame, shown in Figs. Gland "7 in 'asuitable form and then inserting `the plastic matevr-ial through theslots .29'a which extend V"through the rim portions 26. The tapered ,orbeveled 'form otthe negative plates Afacili- V't'ztes A'theirremovalfrom the form Without scraping o' the plastic material and 'lends alsoto 'thestreng'th of the plates. The vari ous negative plate members arepiled upon each other and surround each pair of shaft ,members 14, asshown in F ig. 4, successive znegative pilates 'being separated at theirpe- ,rip'hleries bythe separating conducting members 31. The negativeplates are so propor .tioned as to be slightly smaller than thedimensions of the cell chambers, so that a .space 32 is lett around theplates for the circulation of the electrolyte. A similar space 33 liesbeneath the bottom plate, which lis 4specially formed With a beveled`flange 34 resting upon a beveled portion 35 of the Casing- .Theuppermost negative V,plate is of special ffonm to receive a series ofholding screws or bolts 36 rfor securing` it to the Ysupporting Wall r5.37 represents a series of spool-lile non-conducting separators which arelocated in openings 38 of 'the positive plates and which serve toproperly space V the negative and :positive plates from each other'andprevent them from touching as "the l'result of vibration or warping orVfor other causes. These spools maybe in- :serted in Ythe 'holes 38 inany convenient manner; as for instance by forming one `of its "heads -asa separate apertured disk which .receives the end of the shank afterbeing [inserted through the aperture of the plate. (See Fig. These partswill 'be lheld in position by the piled arrangement o'f the plates. (SeeFig. l.) Bolts 36 also serve as'the vconnections for the electricalcircuit.

'through 44 indicates one ot the usual threaded caps in the cover 7through which water may be introduced into the cells, as desired.Several such caps may be used if desired.

The arrangement described enables the -cell to be readily assembled ordisassembled. By removing all the bolts 9 the cover and wall may beremoved, together with the several positive and negative plates carriedwith them. By also separating the cover land wall 5 the nuts 20 may beremoved so as to enable the plate supporting posts or shafts 'to bedisconnected from the wall 5 after which the negative plates can bepulled out laterally trom between the positive plates. All `parte oitthe battery are vtherefore readily accessible when desired.

LTWhat I claim Vis l. AIn a secondary battery, a battery pate Aofsubstantially 'f5-shape in plan View provided with an opening at Hthecenter of each of the contiguous approximately circular portions toreceive a Ysupporting post.

2. In a secondary battery, a battery plate of substantially S-shape inplan view provided with an opening at the Acenter of each of thecontiguous approximately circular portions to Yreceive a supportingpost, said ,plate being divided into two parts along a lplaneperpendicular "to said plate and through said openings.

3. A secondary battery, comprising a jar having a cell chamber therein,a horizontal wall, a post depending from said Wall, and a series ofhorizontal plates supported by said post and having circular portionsconcentric therewith.

4. A secondary battery, comprising `a jar having a cell chamber therein,ya horizontal wall, a post depending therefrom, and a series ofhorizontally disposed valternating positive and negative Iplatessupported Yby said 'posts and 'having circular Yportions concentrictherewith, oneseries of plates being of two-*part form, and beingremovable `from lbetween the other series oi plates by ihorizontalmovement when the plates are Aoutof the jar.

5. A ysecondary battery, comprising a jar having a cell chamber therein,a horizontal wall, two Lposts depending from said wall, and two Vseriesof horizontal battery plates oi' S-shape in plan View, each plate havingan opening at the center of its contiguous circular portions to receivesaid posts.

6. A secondary battery, comprising a 'jar having a cell chamber therein,a 'horizontal wall, two vposts depending from said wall,

'two series of .horizontal battery plates Yof 8-shape in plan view, eachplate having Ian opening vat the center of its contiguous eircularportions `to receive said posts, and alternate lates beingdivided'alon'g va plane e 'axes of said posts to tenable them to beseparated from the other plates by horizontal motion.

7. A secondary battery comprising a jar having a cell chamber therein, ahorizontal wall, a post depending from said wall and a series ofhorizontal plates removably supported by said post and having circularportions concentric therewith.

8. A secondary battery, comprising a jar having a cell chamber therein,a horizontal 10 wall, a post depending from said wall, and a series ofhorizontal plates removably supported about said post and havingcircular portions concentric therewith.

In testimony whereof I hereby aiix my signature.
